GreenGro Granular Plus Mycorrhizae - 50 lb

Stronger Root Zones for Soil Cultivation - 50 lb Bulk Bag

Roots that struggle to take up nutrients limit growth through vegetative growth and flowering. This granular blend combines mycorrhizal fungi, beneficial root-colonizing bacteria, kelp and humic in one product. The fungi form a network of fine filaments that extends the reach of the root system, and the bacteria secrete enzymes plants use for vigorous growth.

The 50 lb size suits growers who fill many containers, beds or soil batches. Commercial operations and serious indoor growers can use it across repeated transplant cycles and mix it into soil blends. Hobbyists with a small garden may find it larger than they need.

Key Features & Benefits

• Multi-part formula — mycorrhizae, beneficial bacteria, kelp and humic in a single product, so you handle fewer inputs.
• Granular form for soil — made for soil-based applications rather than hydroponic systems.
• Applied at transplant — places the microbes at the roots as the plant moves to its new container or bed.
• Flexible uses — works as an ingredient in soil mixes and in compost teas.
• Bulk 50 lb size — lowers how often you reorder if you run a large soil program.

Who Should Use GreenGro Granular Plus Mycorrhizae

Growers who start plants in soil or soil-based mixes and want to support root development at transplant. It fits commercial cultivation teams, home gardeners who blend their own soil, and anyone who brews compost teas.
